Adding anything exclusive to Linux is just shooting yourself in the foot. Adding new titles isn't going to sway many either, there's still no incentive to switch.

Except that Valve already has ported quite a few of their own games to Linux. Portal 2, TF2, DOTA2, L4D2 and more are already there. It hasn't sped up Linux or SteamOS adoption. SteamOS is nothing more than a PR stunt.

Apple demonstrates that closing hardware platforms and overcharing for them wont help you get away from Microsoft, not that the one true way approach is flawed.

As much as I hate to say this, the real reason why Linux will never be a viable desktop replacement is that there is a lack of standardization and the open source above all else attitude.

If you want people to come to Linux, you need programs for them to use. Not open source programs that they've never heard of, but the same programs they use on Windows. Developers of these programs don't want to support an ecosystem where they're shunned and where it's comparatively harder to maintain on Linux due to any number of factors.

If you want a real user base it's time to stop expecting that you're going to win them over with the benefits such as free as in speech. It just doesn't speak to the majority of computer users out there because the only thing it changes for them is that they're able to see and study something which they cant comprehend in the least.
